SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 709,148, dated September 16, 1902. Application filed May 31,1902. Serial Nn.109,681 (No model.)

T (LZZ whom i 11m/y concern.-

Be it known that I, J AMES EDWIN GIBBs, a citizen of the United States, residing at Staunton,in the county of Augusta and State of Virginia, have invented certain new and useful Improvements in Sash-Fasteners,of which the following is a specification. n

My invention relates to improvements in sash-fasteners; and the object of my invention is the provision of a sash-fastener which will be simple, strong, and durable, easy of attachment, and thoroughly eflicient and practical.

To attain the desired objects, my invention consists of a sash-fastener embodying novel features of construction and combination of parts,substantially as disclosed herein.

Figure l represents a front View of a portion of window casing and sash with my fastener applied. Fig. 2 represents a similar View with a portion of the device dotted to show interior mechanism. Fig. 3 represents a detail view of the parts of the fastener, and Fig. 4 is an edge View.

In the drawings, A designates the window frame or casing, and B designates a sash therein, and to the casing is connected a rack C and to the sash the fastener D, which engagesthe rack and holds the sash at the proper point.

The novelty of my fastener resides in the peculiar and simple construction of the fastener, the case of which consists of the baseplate E, having an upper and lower attaching-lug F, a rim or flange G, and the vertical guides I-I in the upper end thereof upon the base-plate fits and locks, by means of the tongues J, the top plate K, which is formed with a finger-rest L, under which isa slot M, 4o in which works the stem of the sliding fingerrest N, the said stem being connected with the elongated bolt O, which works in the guides l-I of the base-plate, and said boit falls or is pushed into engagement with the toothed wheel P, which engages the rack and holds the sash at any adjustment in the casing.

In the form of my invention shown in Figs. .l and 2 the finger-rest N is pivoted in the sliding bolt O, and when the bolt engages the toothed wheel P the said finger-rest O can bc turned, as shown in Fig. l, and engages the rigid finger-rest L and locks the fastener. In Fig. 3 the finger-rest L turns and engages the rigid Enger-rest N to lock the bolt, and this is an important feature of my fastener.

It will beseen that the bolt is always turned in the guides and will engage the toothed wheel to hold the sash and can be easily released by pressure of the finger and thumb upon the rests. It will also be noted that the fastener can be easily applied without injury or defacement,that the construction is simple, durable, and-cheap, and that the fastener is efficient and practical.

I claim- The sash-fastener herein shown and described, consisting of the casing adapted to be secured to the sash, the Vertical guideway in said casing, the toothed wheel mounted in the casin g under the said guideway, the rackbar to be engaged by said toothed wheel, the bolt arranged in said guideway for engaging the toothed wheel, a finger-piece on the bolt a finger-piece on the casing, one of said finger-pieces being pivoted and serving as a latch to hold the bolt when in engagement with said toothed wheel.

In testimony whereof I afix my signature in presence of two witnesses.

JAMES EDWIN GIBBS.
